Antibiotic resistance and, accordingly, their pollution because of uncontrolled usage has
emerged as a serious problem in recent years. Hence, there is an increased demand to …

Aptamers are single‐stranded oligonucleotides that bind to targets with high affinity and
selectivity. Their use as molecular recognition elements has emerged as a viable approach …

Tetracyclines are a group of important antibiotics with a common four-ring scaffold. While
most tetracyclines are currently used only in animals, their leaching into the environment …

The existence of contaminants in food poses a serious threat to human health. In recent

Nanozymes currently face challenges in respect to their structure, properties, and
mechanism compared to natural enzymes. Single-atom nanozymes (SAzymes) can realize …

A novel cathodic “signal-off” strategy was proposed for photoelectrochemical (PEC)
aptasensing of oxytetracycline (OTC). The PEC sensor was constructed by employing a p …

Oxytetracycline (OTC), one of the largely used antibiotic in veterinary practice has been
banned due to its potential side effects. Development of a field applicable and affordable kit …

Background Aptasensors are promising biosensors with prominent recognition capabilities.
They have fascinated a lot of attention among scholars, due to the excellent characteristics …
